I'd be thrilled to see you compete in the SEO world championship. I got an email from Stéphane, moderator at SEO Sphere, and he told me that many of the best white hat SEO's in France will be participating. December 14, 2006

If any of the contestants sites are using black hat methods, like hidden content, we will disqualify them.
Anyway, the way the actual contest is built and how search engines work, I doubt the winner will succeed with using methods such as comment spam. Wait and see on the 15th of January when we release the final rules, there might be some updates.
If you find anything suspicious, you can always send us an email. The email is up an running now. December 11, 2006
